Grace, a solar EPC service provider offers an extensive range of solar modules suitable for diverse projects and climatic conditions. Grace has introduced high quality Mono PERC solar modules in its solar panel range which offers high efficiency, long life span at the best prices. These panels are gaining momentum in the solar industry with its low installation costs and accelerated ROI. This new invented range of the mono PERC solar module is almost similar to the traditional solar panel, except that the passivation layer of material on the backside of the cells that is all meant to amplify the efficiency as well as the durability of the solar panel.
The introduced mono PERC solar module is also known as passivated emitter and rear cell, which has been applauded in the market for its unmatched performance even in low light and high temperatures. This pioneering range of mono PERC solar panel is tested and certified for meeting all regulatory standards ensuring the best in class performance throughout the lifespan.
We are based in Ahmedabad, Gujarat with an extensive network in India as well as foreign countries. Our entire product range and EPC service are available at every nook and corner, so feel free to contact us, regardless of the region concern.
The light that isn’t absorbed by the silicon cell is reflected again by the passivation layer, giving a second chance to the cells to absorb it, in turn increase the absorption rate and ultimately increase the efficiency of the cells.
The electron recombination is a very common phenomenon in the traditional solar panel that reduces the cell efficiency. The application of the passivation layer helps to prevent the electron recombination and thus boost up efficiency.
Scientifically, a silicon wafer in a solar cell is capable to absorb light in wavelengths up to 1180 nanometers, if the wavelength of the light is more than thereof, it gets reflected and absorbed by the metal back of the solar panels, creating heat. This heat diminishes the efficiency of the solar cells. In contrast, while the passivation layer is applied, it reflects light with a wavelength greater than 1180 nanometer that ultimately reduces heating of the cells and as a result increases efficiency.
